Referring to the drawings: A represents a portion of the machine traine in which journaled a shat't l carrying; at its outer end an eccentric pin Mounted closely adjacent to this end ot the shaft 1 is a workfeeding traine nleniber 8 which may be :lorined as a lever and pivoted at its rear end to swing laterally, as more fully shown in United States Letters Pat-ent 1,elll,688, granted November T, 1929,; Member 3 is tt'orked at its forward end, the forked portions being termed as sleeves 4l and `for the Slidahle reception of the telescopically combined punches and sets shown at tl and T. llixed to the traine A is a bracket 8 having' aY forwardly extending; guide portion l) on which may ride a roller l0 jourualed near the lower end ol a distributing raceway l l. is shown, this raceway is inade double. to provide separate paths 'for the eyelets to present the saine in proper position to the punching and eetl-in mechanisms, Fronte A also carries lixed thereto a bracket ll having' at its outer end an inclined hollov: Sleeve 12 within which is mounted a sleeve 13 (see Fig. 5) depending :iroin a dis tributingr hopper lil, a set screw 15 being provided to 4[ix the hopper let Atroni turning,` relative to the sleeve 12. Jonrnaled within the Sleeve 11,3 is a shalt 16 which may carry at its upper end any suitaljile or usual eyelet agitating` ineens Within the hopper 1li. it one eide the lower lace oli the hopper lil extended as shown at 17 and carries lined thereto by ineanel olthe spacing bars 1S and 'lll a distributor segment 2O by which the eyelets forced outward troni the hopper 11i are nnidctlinto their respective Ways in the ractnva)y member 11. This raceway nieniher is pivoted to the extension 17 at 21 and is provided with a lateral extension 22 havinga a elot- 23 Ylor the. reception oit' a screw 2l. As shown in Figi'. lll. a Washer 2l() through which the screw ill passes is: urged into fontact with the rari-way ll by means ol a :spring lock washer EBLll interposed between il and, the head oil screw lf-l. This construc-L tion allows a limited pivotal movement ol the raeeway about an axis directly in line with the c velet path, but. at the saine time holds the raceu'ay :u fcurately in registering position with relation to the segment 20.

Finch gruideivay of the raceway lneinber ill is slotted vertically throughout the major portion ot' its length in order to allow lint or other 'foreign matter to pass therethrough Without danger of clogging the eyelets therein.

The lower end oli the raoenf'ay is connected to the operating crank 2 by a universally jointed connectingr rod comprisin@` sections 25, 26 and 2i'. rllhe sections are pivotally connected to each other by pivote which pro vide for angular movement ol the raceways and -tor a slight, component' ot lateral nioveinent oli the connecting; rod due to the angular movement oit the raeeways.

Fixed to the toed traine ineinber ffl heturen sleuren el. and is a forwardly entending ineniber 2li-l carrying; near its outer end a double ended combined punch anvil and eet :il in cooperative relation tothe punch and Set inechanienis (i and As shown in Figs. G and "I, eat-,.1 punch and set mechanism comprises an outer sleeve Elfi in one end oli' which ifs Screwed a set 36. The enter :tace oit set 3G has an annular setting surface Si' provided with an axial pertoran tion. A, punch 38 has an extended punch eleiuent 39 which projects through the central perforation olf the eet 2:36, and its rear end has lfoi'nied thereon an enlarged head lll of a diameter to slide within the sleeve and to iinpinge against the inner end of the set 3G. The punch is normally held in projected position with the head Ll() in contact With the end oit the set hy means ot' a plunger Lll having a head 4t2 iinpinging on the head el() and l thereanainst by means ol. a spring` lll snrrmindinp; 'the plunger and bearinn` at its opposite end against, any suitable abutment (not. shown). llaclr o'li the settlingr surtace il? the central perforation ot the set merges with an enlargzjed cavity 414; Within which the punch element 39 may play lreely, and forming therewith an annular chan'iher ot' considerable size.

ln order to prevent the leerling; olE eyelets to the lower punch and eet mechanism. :i stop linger may he employed. this linger inovahle at will into and out oll the path ol the eyelets in the raeen'uy. tlurh a eoinitruotion is shown in llieri. tl and Sl. wherein -li is a lever pivoted at #lo on the lower section oi the raceivav. ihisi lever has z resilient finger portion or handle l" movable between retaining notches or depressions 48 and 4H in a fixed part of the race "ay, The .lever l5 ie termed with a curved extremity lil which is positioned in the path o'l the eyelete ini niediately back oli' the last eyelet when handle t7 engages notch 48. to prevent the flow oif the eyelets, and which le retiactzible troni the eyelet path by swinging the handle to engage notch 48.

)lill lll) Y The operation ofV this mechanism lis as follows: A piece of work is fed either side of the double ended combined anvil and set 34m position toibe punched on the closing,

of the oppositely ldisposedy punches` there-y against, these punches b eingpactu'fatedgin any' suitable manner, by forcing together the mechanisms 6 and:7.f At the startofino/ve the punches the raceways are vretracted, by

the action of the eccentric pin 2, th'espriiig. fingers 28 yielding to allow the tl'ireaded eyelets to pass from the ends of the "race-4 ways, these fingers thereupon closing the open ends to prevent the escape of succeed-l ing eyelets. `The mounting of the raceway allows its motion to be a slight swing about thepivot 2l as a center, jthis pivot being so vpositioned that the lower ends of the raceway move to the front and rear and sub-v stantially at right angles to the line of feed. By arranging the race-way so that its delivery end will swing from front to rear, and by arranging the crank Qnearlydirectly behind said end of the raceway, it is possible to attach the connecting-rod directly to the raceway adjacent to the delivery end. This relation of the crank and raceway permits much lighter parts than those required 'in prior constructions and permits high speed of operation without appreciable vibration.

The raceway extends substantially parallel to the -axis'of the crank-shaft l, and its pivot 2l is adjacent to but behind a line intersecting the inserting locality rand'eX- tendingiparallel to the direction of workfeed, which line is represented in Fig. 5 by broken line a.

After the material has been punched and the raceways retracted ont of the way, further motion of the punching and setting mechanisms toward the work causes the setting elements to force the -eyelets through the work and clinch the same againstthe block 34, the punches being allowed to yield by the springs 43 during this portion of the operation. While these mechanisms are in engagement with the work, the carrying member 3 is movedt laterally to feed the work. On thev retraction of the punch and set elements, the work is freed, and the frame 3 is given va return motion preparatory to a subsequent punching and setting operation.

lith prior constructions including telescopically related punches and sets, it has been found, particularly when working on fabrics, that lint and other foreign mattei' accumulates around the punch elements and is carried thereby back within the setl ele.- ineiits, such accumulations heretofore resulting in a clogging of the punch and set and preventing free relative moveinent thereof. l* oi' thisl reason the p unche'shave sometimes failed to p'ick4 the eyelets from Vthe raceways.

On the other hand, by providing the dirt.

chambers as herein shown sullicient space is allowed for a considerable accumulation n bw fore vclogging is caused. As these punches breaka'fteisome tiine'iii service, it has been found that this chamber may be made of sufficient size to insure'againstcloggingdur .ing theel'l'ectivelifeof thepunch. lVhen the punches are renewed, this cliamb'erv is7 readilycleai'ed of obstructing material.

Vlf the operator wishes to usethe 'upper punch an'dsetting device only,4 as lwlien eye-` lets may have been skipped, the finger portion 47 on4 the lower raceway portionk is moved into'4 engagement with notchv 48" as shownO in Fig. 8, and the end; eyeletis picked outof theraceway. In subsequei'it operas tion of the machine no eyelets are presented to the end of the lower raceway in position to be picked therefrom by the lower mechanism. lVhen it is desired to resume the duplexv setting, finger portion 47 is moved into engagement with notch 48a, which allows the eyelet feed to the lower mechanism to be resumed.

Vilhile this invention has been described in connection with a duplex eyelet setting machine, it is evident thatv features thereof might be*r used with equal advantage in single machines, or'many machines intended kto performV other operations on material.

Having thus described certain enibodiments of this invention, though it is evident that many changes and modifications may be made therein without departing from its spirit or scope, what is claimed is- 1. In a machine -of the class described, fastener-inserting mechanism, a hopper for fasteners, a raceway movable relatively to said hopper and arranged to conduct fasteners from the latter to said mechanism, a pivot connecting one end of said iaceway to Vsaid hopper, means arranged to support the delivery end of said raceway in cooperative relation to said mechanism, an operating crank, and a connecting rod one end of which embraces said crank and the other end of which is connected to said raceway near-its delivery end.

2. In a machine of the class described, a supply hopper, operating mechanism, a main shaft, a raceway pivoted at said hopper and having its free end extending toward said mechanism, a fixed guide, a inember carried by the free end of said raceway and movable on said guide, an eccentric on said shaft, and a link connecting said eccentric and the free end of said raceway.
